Abstract

BACKGROUND

Single coronary artery (SCA) is a rare anomaly with a prevalence of 0.024-0.066%. Some anomalies are merely benign anatomical variants, whereas some can result in myocardial ischemia or life-threatening arrhythmia. . We described seven cases in which all three major coronaries emerged from the right sinus of Valsalva via a single ostium and supplied the vast majority of the myocardium. A smaller branch arising from the left sinus supplied a modest quantity of myocardium in some of those few cases. These SCA variations do not exactly fit into any existing classification. It is unclear whether we need to modify previous classification systems or newer classification systems.

CONCLUSIONS

SCA is divided based on its anomalous course and is usually a benign condition but it may present with cardiovascular complications. Clinicians should be aware of this entity along with the role of CT angiogram in its diagnosis and management.

摘要

背景

单冠状动脉（SCA）是一种罕见的心脏血管异常，患病率为0.024% - 0.066%。有些异常仅仅是良性解剖变异，而有些则可导致心肌缺血或危及生命的心律失常。我们描述了7例病例，所有三大冠状动脉均通过单一开口从主动脉窦发出，并供应绝大部分心肌。在少数这些病例中，有一些从左窦发出的较小分支供应少量心肌。这些SCA变异并不完全符合任何现有的分类。尚不清楚我们是否需要修改先前的分类系统或更新的分类系统。
